A little help overclocking my Celery please...

[Omega]

I have a celeron 600 which I have managed to overclock slightly to 675mhz at 1.6V. Now this chip should be able to get higher, shouldn't it? If I try the next highest FSB (83mhz), the Bios just resets itself to default settings and I have to go back and re-enter all my settings. Trying to overclock to 900mhz results in no posting and a manual bios reset is needed to get back into my system.

Ideas anyone?

My mobo is an Aopen AX6BC Pro
Asus slot converter
Aopen TNT2 ultra
256mb ram (mixture but the slowest is pc100 and has run reliably at 100mhz on another system)
SBLive value
Quantum Fireball 15gb 7200rpm
aopen cdrom
sony scsi burner
ls120
running Win2k pro

Make sure that your heatsink/fan combo is up to it and monitor the temps with Motherboard Monitor or Motherboard Probe. With good cooling the next thing to try is to up the voltage a bit on your socket adaptor. Try another 0.05 volts and slowly raise the voltage. If possible don't increase it beyond 0.2 volts.

This should help you to reach higher FSB's.

yeah upper the Vcore !!!

At 1.6V, that should be a cB0, right? Cooling is always a good thing- if you're still using the stock HSF with the pad between the core and the heat sink, at -least- clean off the pad thoroughly and put a decent thermal compound (Arctic Silver II seems to be the compound-of-choice at the moment) between the core and heat sink. Also, how new is the chip? If it's fairly new, you might try burning it in a bit and then kicking it up. The system-pull cC0 600 that I got did 927 right out of the box. I can't say much on the voltage, since I haven't gotten my own slocket in yet to try playing with it on my own. Good luck!

First, make sure you have good cooling. Heat is the enemy. I wonder if that C-600 isn't really a cC0 stepping with a default of 1.7v and you have the slotket adapter set at 1.5v default? Look at the top of the chip, what does it say the default voltage is?

[Carmine_Paterno]

Actually, it isn't anything anyone recommended. My brother has a Aopen ax63 i believe, and he can get his Celeron II 600 to 750 with stock cooling. He can't go any higher, or lower becuase the motherboard is messed up. My suggestion would be to get A ABIT BF6 and pump that baby to 1 gig +. Of course, before buying a new motherboard, try upping the voltage. I don't think that is what it is because, most 600's can do 900+ @ default voltage. Hope I helped!!!

Gotta agree w/ batboy and Marty here.... Do you have SiSoft Sandra installed?? You can get all of the info from this, w/out having to pull the chip out to read it.

The cC0 stepping is the only one to have the default vcore of 1.7v. anything less is a cB0. If you can, raising the voltage (vcore) up as previously mentioned will help tremendously. As Marty said, keep it under 2.0v. I'd start out at around 1.85 or 1.9v, and see what that does for you.

Not all Celeron 600's (cB0 or cC0) will make it to 900 MHz at the default voltage. Some will, but a good chunk of them won't. Each individual chip is different, and overclocks differently. I own a pair of the cC0 600's, and;

1) Neither will hit 900 at default.
2) One maxes out at 945/1.9v. Regardless of more vcore, that's it for that chip. 945.
3) The other one made it all the way to 1053 MHz at 2.05v. I ran it there for a while, then backed it below 2.0v (to 1.95v) to let the chip live a bit longer. At 1.95v, it runs stable up to 1020 MHz.

See if you can get the info on that chip of yours, and post it here.

*edit* BTW, Omega, I just noticed this was your first post. Welcome to the forum!!!

Well, I hate to correct or disagree with a senior member :) but Marty actually said, don't increase the voltage more than 0.2 volts, which I agree with totally since we don't really know what cooler he's using, I'm not sure I'd advise running it at 1.9v unless he has really good cooling.

Nope, you're right....I got dyslexyc for a minute there....musta read that as 2.0.....

True enough. With good cooling, a cC0 will go at 2v for a while, but I wouldn't run a 1.5 or 1.6v chip there, either.

My bad....sorry 'bout that.

Are you saying that 1.95v on my cel600@900 w/factory intel heatsink/fan is a bad idea?

With the intel hsf, yes.

With a 1.5 to 1.65v cB0 chip, yes.

With a 1.7v cC0 chip, with a good quality high performance (read, Alpha, GlobalWin, etc...) hsf, no.

Higher vcore settings increase the temperatures a fair amount. It's highly recommended when running that fast to upgrade to a better hsf than the intel unit. Don't bother with the Gorb, either, as 900 is about their limit for effective cooling, as well.

There's a whole bunch of great hsf reveiws in the "Tips and Techniques" section on the left hand side of the front page. The info there can help immensely in choosing a replacement for your intel hsf.

Running 1.85V on a retail HSF (with Arctic Silver applied), the best I was able to achieve was 810MHz (not 100% stable) at 39C. I would not have wanted to increase my voltage beyond that without MUCH BETTER cooling. I am now running at 900MHz (100% stable) and can go as high as 945MHZ, at 1.79V. I am watercooled to 2C over ambient. I too have a cB0 core, and I highly recommend that you get better cooling before you push the voltage to 1.85V or beyond. Better cooling makes a huge difference with these chips.

[batboy]

Spacepiston, the short answer is yes, it's a very bad idea to run 1.95v with a retail heatsink/fan.

[Sohryu Asuka Langley]

that would mean my Pin wiring to my cBo 700 to run 2.05v is bad right? I have a K7 1Ghz rated Heatsink with a slightly better fan then what cam with it... compound from teh little packet that came with a blue orb...

Sandra still says it 1.6v.... damn...

[LutaWicasa]

This is of course just my opinion. If you are OC'ing at all the stock HSF is a bad idea. From things I've read at various boards the Orb line is not much better. From personal experience the Alpha Pal 6035 does an outstanding job assuming it is properly mounted. OC'ing my Celly with my Pal, my CPU temp has never exceeded 40c. Remember also that if you use a high output fan, its a good idea not to use the fan header unless you have a newer board rated for such a load on said header. Ask questions, try stuff, have a ball :)

Running it at standard spec with the Retail HSF is bad news... :¬)}

Seriously tho, the factory 'sink is poor compared with all but the cheapest of the cheap OEM Sinks. If you can afford one, get a GlobalWin. I run the FKP32 (forerunner of the FOP) It's a good 'sink, or an Alpha (although be careful of the clip) I bent mine while removing it. £35 heatsink made useless buy a bent clip- Never mind I know now...
